Created attachment 136245 [details] dc-mirroring-journal Same machine as on the https://bugs.freedesktop.org/show_bug.cgi?id=104281 but reproduced on multiple ACER laptops. Using the latest Linus master compiled with CONFIG_DRM_AMD_DC_PRE_VEGA=y we have that sometimes the image on the internal panel gets corrupted when mirroring on an external HDMI display (see [0]). We have verified that this is a regression introduced by the DC code. In attachment the journal output. [0] https://imgur.com/a/rnItJ
